This isn't Clooney's first time working with the coffee company, however. The 54-year-old actor has represented the Swiss brand internationally since 2006.

Devito and Clooney are longtime friends, and have never been shy about their bond, especially when it comes to drinking.

"We end up on the front of the [New York] Post every time we hang out so we have to be really careful," Clooney told ET back in March. Their drink of choice? Limoncello's!
